Application of minimum principle of potential energy with mixed variable for large deflection beams to calculating deflection surface equation

应用大挠度弯曲直梁混合变量最小势能原理,求解了二种边界条件的大挠度弯曲板条的挠曲面方程,并把求得的结果与经典的结果相比较,本文所得结果具有较高精度。

According to the principle of minimum potential energy with mixed variable for beams with large deflections, the deflection equations of cylindrical bending of infinite-length rectangular plate in different limit conditions are calculated. In contrast with classic results, the results obtained in this paper have a higher accuracy.
